错误: strpos():将来,非字符串针将被解释为字符串。使用显式的chr()调用将当前行为保留在
已经阅读了许多在线主题-他们似乎都没有触及到我如何编写代码,这使我不确定自己在哪里错了。
此代码使用get搜索文本文件,并通过该搜索返回文件数组。代码一直工作到7.3更新。

$ search_get在这里无效吗?
答案 0 :(得分:1)
@ paul-t是正确的,您正在分配变量而不是将其与null进行比较,这就是为什么您应该使用所谓的Yoda conditions
if (null === $search_get) {
$search_get = 'encyclopedia';
}
无论如何,这是代码的稍微简化的版本:
$search_get = @$_GET['q'] ?: 'encyclopedia';
foreach (glob("dir/*.txt") as $search) {
$contents = file_get_contents($search);
if (!empty($contents) && false !== strpos($contents, $search_get)) {
$found[] = $search;
}
}
BTW考虑使用stripos
代替strpos
,因为当前对$contents
变量的检查区分大小写。
